Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically a traction device for agricultural machinery. Background Technology

[0002] Towing, as a key technology in modern transportation and engineering operations, generally refers to the process of using the power system of a motor vehicle to move a platform or equipment that does not have autonomous driving capabilities. This technology is widely used in many fields, including car rescue, engineering machinery transportation, and agricultural equipment movement. In car rescue, a tractor unit uses a special device to safely tow a disabled vehicle away from the scene. In the engineering field, heavy-duty tractor units can transport large machinery such as excavators and bulldozers. In agricultural production, tractors use traction devices to drive agricultural implements such as seeders and harvesters. Towing operations not only improve equipment utilization but also greatly enhance work efficiency. With the development of technology, modern traction systems are equipped with intelligent control systems and safety protection devices to ensure the safety and reliability of the operation process. In addition, the application of traction technology is also reflected in professional fields such as railway transportation and ship towing, providing important support for the development of modern logistics and transportation industries.

[0003] However, it still has some drawbacks. For example, existing traction devices often rely on a single-direction buffering mechanism when starting and stopping, lacking a two-way buffering design. This results in an inability to effectively absorb impact forces during acceleration and deceleration, reducing the system's reliability and lifespan. Furthermore, the replacement process for the existing device's traction hook is cumbersome, typically requiring the disassembly of multiple components and lacking a quick-replacement mechanism, increasing maintenance time and operational complexity. These drawbacks not only affect work efficiency but may also lead to equipment damage or safety accidents.

[0004] To address the aforementioned problems, this application proposes a traction device for agricultural machinery. Utility Model Content

The bidirectional buffer traction head facilitates buffering during acceleration or deceleration when a vehicle is towing agricultural machinery, preventing damage to the machinery or accidents caused by physical collisions. The quick-release replacement turntable for the traction hook facilitates the replacement of different traction hooks, thereby meeting different usage needs and showing good application prospects.

[0007] Preferably, the quick-release turntable surface of the traction hook has a detachable traction hook kit, one side of which is fixedly connected to the traction hook body, a limit bolt is installed above one side of the bidirectional buffer traction head, one side of which is fixedly connected to a damping plate, and the damping plate has two sets.

One side of the threaded post is fixedly connected to the quick-release replacement turntable of the traction hook, and one side of the quick-release replacement turntable of the traction hook is fixedly connected to the hook mounting rod.

[0010] Preferably, a limiting groove is provided on one side of the hook mounting rod, the limiting groove is movable inside the rotating groove, the rotating groove is interconnected with the bolt groove, a threaded rod is movable inside the bolt groove, and the bolt groove is provided above the bidirectional buffer traction head.

When replacing the detachable traction hook kit, the limiting bolt is loosened, so that the threaded rod leaves the limiting groove. At this time, the quick-release replacement turntable of the traction hook is rotated, and the threaded rod is rotated out of its interior through the engagement of the threaded column and the threaded groove. At this time, the detachable traction hook kit can be removed from the hook mounting rod for replacement.
